I downloaded Google Earth this morning and just spent the past two hours having my mind boggled. For those who might not be familiar with Google Earth, it is a software application that allows you to effortlessly zoom in on most anywhere you would want to go, certainly in North America, but actually on much of the planet, via an incredible database of satelite imagery. I had a great time exploring Guadalupe Mountains National Park and then some of the central Texas lakes and rivers; scouting out future kayaking adventures.

Have fun, and prepare to "waste" a whole lot of time!
